What does that look like? I mean, these various numbers are tossed around like so many doggie treats, so I thought I'd take Google Sketchup out for a test drive and try to get a sense of what exactly a trillion dollars looks like.

We'll start with a $100 dollar bill. Currently the largest U.S. denomination in general circulation. Most everyone has seen them, slighty fewer have owned them. Guaranteed to make friends wherever they go.

A packet of one hundred $100 bills is less than 1/2" thick and contains $10,000. Fits in your pocket easily and is more than enough for week or two of shamefully decadent fun.

Believe it or not, this next little pile is $1 million dollars (100 packets of $10,000). You could stuff that into a grocery bag and walk around with it.

While a measly $1 million looked a little unimpressive, $100 million is a little more respectable. It fits neatly on a standard pallet...

And $1 BILLION dollars... now we're really getting somewhere...

Next we'll look at ONE TRILLION dollars. This is that number we've been hearing so much about. What is a trillion dollars? Well, it's a million million. It's a thousand billion. It's a one followed by 12 zeros.
